Scilab Function
Last update : April 1993

funptr - coding of primitives ( wizard stuff )

### Calling Sequence

  `[numptr] = funptr(name)`

### Parameters

- `name`: a string, the name of a primitive
- `numptr`: the internal routine number of the primitive

### Description

Utility function (for experts only) to get the internal routine number `numptr` of the primitive `'name'`. `numptr` is formed from the interface number `fun` and the routine number `fin` of the primitive in its interface by `numptr = 100*fun + fin` (fin < 100). From `numptr` you can get the interface number `fun = floor(numptr/100)` which may be useful to link a dynamical interface with arguments passed by reference (see example section).

### Examples

    // Suppose you want to load some codes via the dynamic
    // loading facilities offers by addinter. By default
    // arguments are passed by values but if you want to
    // pass them by reference you can do the following
    // (name being the scilab name of one of the interfaced
    // routines) :
    //
    // addinter(files,spnames,fcts)  // args passed by values
    // num_interface = floor(funptr(name)/100)
    // intppty(num_interface)  // args now passed by reference
    //
    // Note that if you enter the following
    //
    // intppty()
    //
    // you will see all the interfaces working by reference
